Keyence 5000 bit question

[Terry B]

New to Keyence--can some one clarify the difference between
MR20000 output & LR20000 output bit. Having to rework a machine and just trying to get my feet wet before going too far. Any help will be appreciated

Thanks Terry

MR20000 output bit - Internal Auxiliary Relay - Non memory retentive, when power goes off to the PLC this returns to an Off or 0 state.
LR20000 output bit - Latch Relay - Memory retentive, when power goes off to the PLC this maintains the last state when power is restored.

Regards,

How do you reset the LR ? The code that I'm looking at doesn't show any type of reset--getting it back to the off state.

Thanks
